Specification of Letters Patent.

Application filed July 22, 1910. Serial N 0. 573,246.

To all whom it may concern:

Be it known that 1, WILLIAM E. CooNnY, a citizen of the United States,and resident of Cleveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvements in Adjustable Cleanersand Smoke-Consumers for Locomotive Smoke-Boxes, of which I herebydeclare the following to be a full, clear, and exact description, suchas will enable others skilled in the art to which itappertains to makeand use the same.

The objects attained by the invention are primarily the equalization ofthe draft through the boiler -fiues by providing suit able draftpassages therefor through the smoke box, the walls of which are soarranged as to permit of free circulation through all the flues withoutchoking any of them with cinders, or with the products of combustion,and whereby the free consumption of coal will be permitted and the draftwill tend to remove all accumulations of soot or cinders in the fiuesand passages and prevent deposit thereof in the smoke box. By theimproved construction hereinafter described the life of the boiler isincreased and its action rendered more useful in an efficient andpractical manner.

The invention is designed to provide means for accomplishing thefollowing results: the removal of all obstructions to the free action ofthe draft, through the smoke flues and smoke box, and thereby toequalize the draft through all the tubes, and avoid the retarding of thedraft at any point in the smoke box, and in particular to prevent thechoking of the upper fines; to so arrange the draft passages in thesmoke box that the draft will scour the smoke box and prevent thedeposit therein of soot and cinders; to assist in consuming the soot andsmoke by relieving the flues and grate from back pressure; to relievethe strain upon the bottom flues in the boiler by insuring free actionof the draft in the upper fines, and by equalizing the draft to reducethe amount of coal consumed, and keep the fire clearer and the steampressure steadier and to dispense with projecting castings or pockets inthe front end, heretofore employed as cinder catchers; to avoid theoverheating and warping of steam pipe joints in the smoke box, due

to deposits of hot cinders thereon, which can only be removed withdifliculty.

The invention further comprises the forms of construction andarrangement of said walls and the means for adjusting the relative sizesof openings in said passages, and in the screens provided for preventingthe escape of incandescent cinders or sparks from the stack, ashereinafter described, shown in the accompanying drawings andspecifically pointed out in the claims.

In the accompanying drawings Figure 1 is a longitudinal section of thefront end of a boiler showing the arrangement of passages in theimproved device. Fig. 2 is a front view thereof with the head or closureremoved showing the arrangement of the screen and deflecting walls ofthe draft passage. Fig- 3 is a detail view showing the means ofattaching certain of the adjustable plates.

In these views 1 is the boiler, 2 is the boiler head, 3, 3, the fiues, 4is one of the steam pipes for live steam, 5 is the exhaust steam nozzlewhich is adapted to discharge into the smoke stack 6 vertically aboveit, for the purpose of accelerating the draft.

7 is the smoke box to which the steam nozzle and smoke stack areattached. The smoke and products of combustion from the boiler flues 3,3, are not led directly to the smoke stack 6, but first traverse thesmoke box 7 and the smoke from the upper and central lines is deflecteddownward by an inclined partition or wall 8, and passes through ahorizontal passage P formed between a perforated steel plate 9 above anda horizontal wall 10. A portion of the smoke passes upward through theperforated plate 9.

An inclined wire screen 11 connects the forward end of the perforatedplate 9 with the top of the smoke box, and the smoke and gases fromcombustion pass readily therethrough but cinders and large incandescentmasses of soot will not pass through but will remain in the lower partof the smoke box until by churning action of the draft they become fineenough to pass through the screen.

The draft from the central and lower fiues is separated by means of theinclined transverse walls 12 and-18. These walls are inclined inopposite directions forming a V with the points toward the rear. Thedraft which follows the plate 13 is deflected to the bottom of the smokebox and passes to its forward end where it is guided to the screen 11 bymeans of the transverse walls 1 1 and 15 wall 14L being downwardly andforwardly inclined, and wall 15 joined thereto being upwardly andforwardly'inclined. Plate P is slidable 011 plate 12 and regulates thesize of passage P.

By means of the central passage I the draft from the upper and centralflues is deflected with very little resistance into the smoke box 7 andit exerts a scouring action upon the horizontal walls so that they arekept perfectly clean from deposits. The draft from the lower fiues alsoserves to scour the bottom of the smoke box, and the deflecting platesor walls 1 1 and 15 serve to direct the draft against the front wall 20of the smoke box and thence upward to the screen 11, thus producing achurning action which quickly breaks up cinders or masses of soot sothat all products of combustion can pass through the screens in a finelydivided state free from large or dangerous sparks. This arrangement ofdraft passages serves to make the draft instrumental in scouring andkeeping them clean, and prevents deposit in the forward end of the smokebox. It also provides means for securing perfect combustion of fuel uponthe grate and obtains economy in its use and also the amount of smokeand soot produced is much reduced.

The horizontal screen 9 is preferably formed of perforated sheet metalto give a smooth surface so as to avoid friction and retarding of thedraft. The plates 12 and 13 and 1 1 and 15 can be made adjustable toincrease or decrease the relative sizes of the passages, by means ofbolts 21, 21, located in slots 22 in the plates, and in this manner thedraft can be closely regulated. Plate 12 is connected with plate 10 bymeans of the intervening plate 50 having a downwardly turned flange atits outer edge, such.

flange being provided with a slot for the reception of a securing bolt51.

The plates 13 and 15 are positioned angularly to give the requireddirection to the draft.

Having described the invention what I claim as new and desire to secureby Letters Patent is;

1. In combination with a locomotive boiler, its fiues, smoke box andvertical exhaust nozzle, and smoke stack, therein, a horizontaltransverse plate beneath the nozzle opening, and a parallel horizontalscreen above the plate, said plate and screen forming the walls of ahorizontal draft passage, an inclined screen connecting the forward endof said horizontal screen with the top of said smoke box, an inclinedplate connecting the rear end of said screen with the forward end of theboiler above the flues, a
